Question 225: Ray Optics

Question

The variation of refractive index of a crown glass thin prism with wavelength of the incident light is shown. Which of the following graphs is the correct one, if Dm is the angle of minimum deviation?

Accepted Answer

Since D
m
= ($$\mu $$ $$-$$ 1) A & on increasing the wavelength, $$\mu $$ decreases & hence D
m
decreases.
